DISK SCOURING POLISHING APPARATUS;

2 -Application filed July 24, 1922. Serial No. 577,029.

Apparatus, of which the following is a complete specification.

This invention relates to disk cleaning, scouring and polishing machinesand has for one of its objects to produce a construc: tion wherebycircular articles such as disk plows, coulters, harrows and the like,may be readily cleaned and polished.

Another object is to produce a device of the character mentioned inwhich the cleaning box is so mounted that the working load may begradually imposed on the operative parts of the machine.

A still further object is to provide protective housings for thebearings of the machineand to make possible the quick and easy removalof the shaft.

With the objects named inview the invention consists in certain noveland useful features of the construction and organiza-' tion of parts ashereinafter described and claimed: and in order that it may be fullyunderstood, reference is tobe had to the accompanying drawing, in whichFigure 1 is a side view, partly broken away and in section,iof a machineembodying the invention.

Figure 2 is an end view of the same. Figure 3 is a view of the oppositeend of the machine from that of Figure 2.

Figure 1 is a top plan'view of the machine. Figure 5 is an enlargedcentral vertical section taken through one of the split bearings of theinvention.

In the said drawing, where like reference characters identifycorresponding parts in all of the figures, 1 and 2 respectively indicateend standards which rest on the ground or other suitable support and areconnected together at their upper ends by a rectangular frame 3, and attheir lower ends are secured together by means of a rectangular mixturecatching receptacle 4, hereinafter referredto.

Each of the standards 1 and 2 is formed with a vertically extending slot5 to provide guides for a cleaning box 6, provided at its opposite endswith ears 7 received within the slots 5, and adapted to be filled with amixture of coarse sand, grit, gravel or the like, and water. As thecleaning. box, when full, is quite heavy and as the contents thereofimposes a large frictional load on the driv-.

ing mechanism of the machine when the disks to be scoured are embeddedtherein, we have provided means for. elevating the box gradually so asto gradually impose the load on the machine. The elevating means, asillustrated, consists of'a pair" of jacks 9 resting on the bottom of therecep-. tacle 45, and abutting the bottom of the cleaning box at theirupper ends.

The jacks 9 are adapted for simultane ous operation by means. of alongitudinally extending gear-'wheel-equippedoperating shaft 10 providedwith .an' operating collar 11 of any suitable sort. It will be apparentfrom the construction just described that upon the operation of theshaft '10, the jacks 9 will be simultaneously operated to liftthe'cleaning box.

In order to provide means for convenient.- ly removing the contents ofthe cleaning? box,

one of' its sides is provided withga door 12 hinged at 13, and heldinclosed position by means of a longitudinal bar 141 engaged at itsopposite ends in notched arms 15 extend ing from the ends of the box, asillustrated. It will be apparent from the drawing that upon the removalof the bar, the door 12. Wlll immediately swing open under the 1m petusof the weight of the cleaning material, and permit the box to emptyitself into the receptacle 4. I

The end standard 2 is formed witha projecting right-angle shaped arm 16providing a supporting structure for a shaft17-provided at its oppositeend with a bearing in the standard 2. J ournaled on the shaft 17 is anoperating belt wheel 18, and formed integrally therewith is a gear wheel19.

Journaled near its opposite ends in the upper extremities of thestandards is a square shaft 20, and pinned on one end of said shaft is agear wheel 21 in mesh with the gear wheel 19, the opposite end of theshaft being secured in position by means cured to the top of thestandards, and

being pivotally secured-to the portion 26, as .at 31 (see Figure 5). Thefree end of the bearing portion 29 is clamped down in position over thebushing 28 by means of a bolt 82, equipped with a winged clamping nut 33and received within the bifurcated ends of the bearings, as illustrated.In this connection it will be understood that the shaft opening 32 inthe guard housing is circular to permit the shaft to rotate freely.

The operation of the machine is as follows: The split bearings areopened and the shaft is removed. The set collar 22 is now removed fromthe end of the shaft together with the bushing 28. The disks 24 and thespacing collars 25 are now threaded on the shaft, the bushing 28returned to position, and the shaft is remounted on its bearings, andsecured by the repositioning of the set collar 22. Power is now appliedto the belt wheel 18 to rotate the shaft 20 and its disks. The cleaningbox 6 having been filled and in its lowermost position, is now slowlyelevated through application of power to operate the jacks, the disks 24thus being gradually embedded in the mixture, and the load created bythe friction between the disks and mixture is consequently graduallyimposed on the source of power.

It will be apparent that pending the cleaning operation, the housings 27and 30 will eficiently prevent the entry of sand or grit into thebearings. After the termination of the cleaning operation, the cleaningbox is again lowered, so that the shaft and disks may be readily removedfrom position without having to overcome the friction bctween the disksand cleaning mixture.

From the above description, it will be.

apparent that we have produced a machine of the character describedwhich possesses all of the features of advantage set forth as desirable,and while we have described and claimed the preferred embodiment of thesame, we reserve the right to make all changes properly falling withinthe spirit and scope' of the appended claims.

We claim 1. In a polishing machine, the combination with a pair ofstandards, each formed with a vertical slot, a rectangular frame connecting the upper ends of said standards, split bearings carried by saidframe in substantial alinement with the vertical axes of said standards,a horizontal shaft journaled in said bearings, driving means secured toone end of said shaft, and a polishing box provided with ears engaged inthe slots of the standards and adapted to be adjusted vertically and inits uppermost position having its upper edge received within saidrectangular frame.

2. In a polishing machine, the combination with a pair of standards eachformed with a Vertical slot, a rectangular frame connecting the upperends of said standards, split bearings carried by said frame in substantial alinement with the vertical axes of said standards, guardsformed integrally with said bearings and projecting within saidrectangular frame, a horizontal shaft journaled in said bearings,driving means secured to one end of said shaft, and a polishing boxprovided with ears engaged in the slots of the standards and adapted tobe adjusted vertically and in its uppermost position having its upperedge received within said rectangular frame.

In witness whereof we hereunto aflix our signatures.
